BEABING-PULLEE'.

Specification of Letters Patent.

Patented Feb. 15, 1916.

' To all whom it may concern:

Be it known that I, ERNEST P. CAMPBELL, a citizen of the United States,residing at Stockton, in the county of San Joaquin, State of California,have invented certain new and useful Improvements in Bearing- Pullers;and I do declare the following to be a clear, full, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the characters of reference marked thereon, which forma part of this application.

This invention relates to improvements in implements or tools forpulling bearings of all kinds from shafts and .particularly relates to atool for pulling magneto bearings from their respective shafts, theobject of the invention being to produce such a tool as will beadjustable to any sized bearing and which will accurately andefliciently clamp. and pull the same from the shaft in a rapid andeffective matter.

A still further object of the invention is to produce a simple andinexpensive device and yet one which will be exceeding effec- .tive forthe purposes for which it is designed.

These objects, I accomplish by means of such structure and relativearrangement of the parts as will fully appear by a perusal of thefollowing specification and claims.

On thedrawings, similar characters of reference indicate correspondingparts in the several views.

Figure l is a side elevation of the complete device. Fig. 2 is asectional view taken on a line X-X of Fig. 1. Fig. 3 is an end view ofthe tool.

Referring now more particularly to the characters of reference on thedrawings, the numeral 1 designates the shaft and the numeral 2 thebearing to be pulled therefrom.

My improved tool embodies primarily a threaded pin 3 provided with anoperating handle or cross-head 4. The engaging member of the toolcomprises a plurality of engaging jaws or finger members 5 havinginwardly projecting engaging flanges6, said finger members 5 beingslightly tapered and provided at their lower ends with threadedshanks 7screw mounted upon the threaded pin 3 and held in that position by meansof a collar 8 circling the said shanks 7 and secured thereto by means ofscrews 9 which fit into holes 10 slightly larger in diameter than thescrews 9 to allow the finger members 5 to have a slight relative radialmovement for the purpose of engaging bearings of different diameters. Aknurled collar 11 is provided to slip over the finger members 5 andclamp the same against the bearing 2. The threaded pin 3 is then movedagainst the end of the shaft 1 by means of the member 4 and this actionadvances the tool and incidentally-the bearing to which it is attachedalong the shaft 1.

From the foregoing description it can readily be seen that the inventionembodies a single tool having a varied range of uses for removingdifferent sized bearings.

From the description above, it will further be seen that I have producedsuch a device as substantially fulfils the objects of the invention asset forth herein.

While thisspecification sets forth in detail the present and preferredconstruction of the invention, still in practice, such deviations fromsuch detail may be resorted to as do not form a departure from thespirit of the invention as defined by the appended claims.

-Having thus described my invention, what I claim as new and useful anddesire to secure by Letters Patent, is:

1. A hearing puller comprising a plurality of finger members havingradial movement with respect to each other, means carried by the fingermembers for clamping them against the bearing and a pin threaded throughthe finger members and arranged to be advanced against the end of theshaft to move same through the hearing as described.

2. A device of the character described comprising a threaded pin havinga handle, a plurality of finger members each having a shank threaded onsaid pin, a collar surrounding said finger members and secured theretoby screws projecting through said collar member and into orifices insaid finger members, said orifices being of greater diameter than saidscrews, and means moving over said finger members and adapted to holdthem in fixed position with respect to each other, as described.

3. A device of. the character described comprising a threaded memberhaving a handle, a plurality of finger members screw mounted en saidthreaded member, such fin- In testimony wherebf I a'fiix my signagermembers being slightly tapered, a. co1- ture in presence of twowitnesses.
